What laboratory finding is typically seen in hepatocellular carcinoma?

Hepatocellular carcinoma (HCC) is a primary liver cancer that is commonly associated with certain laboratory findings, one of the most significant being an elevated level of alpha-fetoprotein (AFP). AFP is a protein produced by the liver and yolk sac of a developing fetus, and its levels typically decrease after birth. In adults, particularly in cases of hepatic malignancy, high levels of AFP can be indicative of liver pathology, including HCC.

Patients with HCC often demonstrate significantly increased AFP levels, which can be used not only for diagnosis but also for monitoring treatment response and disease progression. While elevated AFP is not exclusively specific to HCC, it is present in a substantial percentage of cases, especially when the tumor is large or when associated cirrhosis is present.

Other findings in the context of HCC might include varying liver enzyme levels, but they can be normal or elevated based on the individual's liver function and the presence of cirrhosis or other liver diseases. Thus, elevated AFP is the hallmark laboratory finding typically associated with hepatocellular carcinoma.
